Application filed June 28, i915. Serial No. 3G,729.

To f/Z "NF7/,017i 'it 1110.3/ concern it known that l, .osirri B.Homin', a ."iliyen oi the *initcd States, residing at iroolilvn, in thecounty ol2 Kings and Siate oi New York, have inveuteifl a certain newand useful improvement in Portable Heat- Devices, of which the followingL ,t fiiication.

The invention relates to portable heaters of' the type which comprises afolding stand, a cup supported thereby, and a fuel-holder received insaid stand below saidcup.

The. invention consists in the construction of the stand, and of theadjustable supporting ring `for the cup, as more particularlyhereinafter set forth.

In the aceon'xpanying drawings-Figure l is an elevation of my portableheater. Fior. is a 'plan viei'vv of the stand with the cup removed. Fig.3 is a detail View in section on the line 3, 3 of Fig. l. Fig. 4 is atop view of the cup, showing the stand, supportingring, and iuelreceptacle packed therein.

Fig. 5 is a bottom view of the stand, but

exhibiting a inodilied construction. Fig. 6

is a, perspective View of the supporting ring` A`o 'from a single piececi Wire.

zunilar i'iunihers and letters of reference indicate like parts.

'he 'principal parts of my heater are the cup the suppi'irting ring Btherefor, the folding stand C, and the cylindrical fuel holder D. ri'hecup .fi with its pivoted han dle l and cover is of well knownconstruction. rlie fuel holder D is the usual can containing so-ealledsolidiied aleoholnow commonly sold on the market.

'i :e stand C' is constructed in the following manner: 4i is a metalplate. 5, 6, 7 are supporting legs stamped from sheet metal and Aformingay tripod. A shown in Q. one ot the legs, as 5. may be rigidly securedto plate si in any suitaliie way, as, 'for example, by a lug i) on',"rroiection S which is inserted in a hole in plate 1i and has itsYirotruding ends lia'ii'onaered .iown or upset, so that the lug forms arivet joining the leg rigidly to the plate. The logs il and 7 havesimilar inward projections if), il, on cach of wl'iich is an ear i2, 13.'Flic ear on 'pi'(.,ii':etioi'1 1C is turn-ed in 'the opposite dirertion to the ear i on prfdectiou il, shown in )Rigi i5, i nd sa' theola* (En i' y 'e pi voted il i . iat when the legs 6, 7 are in openposition, as shown in Figs. l and Q, said legs will meet said stop-s. 7toward the fined Ly swinging the G,

:3, said legs may he folded shown in Fig. ir. rlhe dimensions of i areto lie such that when so folded to-gcil'ie they may be packed in thecupe..

ln order to cheapen the manufacture of the stand, may adopt the modifiedform shown in Fig. 5. Here the leg is provided with an ar/ 16, pivotedto the plate Ll, and all the ears on the several legs are turned in thesame direction. This makes all three legs precisely alike,interchangeable and ca* pable of being stamped out by the saine die.

In the upper end ot' each leg is anotch forming a shoulder l?. Each ofthese shoui.- ders is received in a notch-1'7" formed in the lower edg'cof the supporting ring l The ring B is a hand of metal having at one enda slot 18, into which enters a tongue l5), formed near the opposite endo'f said ring, said tongue being bent over, as shown in Fig. l. Byreason of the free sliding movement of the tongue 19 in the slot 18, thering may be reduced in diameter so as to be pac {"d in the cup A, shownin Fig. 4, the resiiiency of the ring then holding it closel against thecup Wall. Then the ring is i. moved from the cup and seated upon thelegs, as shown in Fig. l, it expands suiiiciently to permit the cup toenter it, while the bottoni of the cup rests upon 'the shoulders l?.yflic cup is, therefore, tightly held by the ring, which also serves asa lateral support for the legs, with which it engages; so that the ringserves the double purpose'i as a-stay for the legs and as a means ofpreventing disi'ilaccmcnt of the cup.

instead of making the ring in the form of a metal hand, as described,may malte it of spring wire, as re'irescnicd in Fig. 6, the criinps Q()in said wire then taking the place of the notches and engaging in likema' with the shoulders on the legs. The ends the wire ring simplyoverlz'ip.

'The 'l'uel can l is reeeiied lietii'een the vertical inner edges of thelegs, as shown in llig. 1, and rests upon the 'plate 4. liilhea allthree legs are pivoted tojthc plate 4, the can 'in .v rest upon thepivot heads. and so he eveniiy supported, The size of the can preferablyto he such :is to permit its lieing packed in the cup together with thestand and supporting ring.

I claim 1. A portable heating device of the type set forth, comprising acup, a tripod 4having its legs pivotally connected for movement in acommon horizontal plane, said legs having shoulders at their upper ends,and a. spring ring having its ends slidably connected; the said ringbeing variable in diameter to it Within said cup or to receive said cupwhen in engagement with said legs.

2. A portable heating device of the type set forth, comprising a cup, astand having a support, a plurality .of legs foldable one upon the otherand'connected to said support, and an adjustable `supporting ring having notches engaging the upper extremities of said legs when in openposition: the said ring being variable in diameter to it Withinand`shoulders at their upper ends, and a spring ring having its endsfree and slidable upon one another, and having notches in its edgeconstructed to receive and rest upon said shoulders: the said ring beingadapted to lhold said cup.

In testimony whereof I have atlixed my signature 1n presence of tWoWitnesses.
